Assuming that light rays approach the black hole from the right side, shadow and photon sphere are formed from the deflection of light corresponds to the Figure 6. The light trajectories in the space-time of Schwarzschild, quintessence Schwarzschild, Hayward and quintessence Hayward black holes are plotted in panels (a) to (d). As can be seen, by increasing the magnetic charge \(g\)  the shadow radius decreases, while in the presence of quintessence matter an enhancement in the absolute value of \(\omega \)  increases the shadow radius which is in agreement with Table 2. The top row shows the results of the Schwarzschild and quintessence Schwarzschild black holes while the bottom row shows the results of regular Hayward black holes in the absence and presence of quintessence matter. By comparing figures (a) with (c) and also (b) with (d), we find that by increasing the magnetic charge \(g\)  the light deflection is smaller, namely the presence of magnetic charge cause to decrease the strength of the gravitational field and thus diminishes the light bending angle [1]}. On the other hand, comparing the results of figures (a) with (b) and also results of (c) with (d) show that the presence of quintessence matter increases the deflection of light rays [2]}.
